So in this problem, what we want to do is write the inequality to represent the following constraint.
00:06
So we're told that a candidate is going to spend no more than $8 ,900 on radio and tv advertising.
00:12
And we're told that radio spots cost $160 each, and each tv ad costs $760 each.
00:20
So what we want to do is we're going to let x represent the number of radio.
00:24
So i'm going to put that here.
00:25
And y is going to represent the number of tv ads.
00:28
Okay.
00:29
Well, we're talking to let x represent the number of tv ads.
00:30
Told that he can spend no more than 8 ,900, meaning what he spends on the radio plus what you spend on tv has to be.
00:38
Well, if you can't be more than it, that means you can be less than or equal to 8900.
00:44
So now we have to represent the cost for radio and tv ads...
